Abstract
The invention discloses an operation counting device of a universal breaker. The operation counting device comprises a support, a counter, a pull bar and a spring, the support is fixed on a breaker operation mechanism, the counter is fixed on the support, one end of the pull bar is connected to a main shaft of the counter, the other end of the pull bar is connected with one end of the spring, and the other end of the spring is connected to a movable pin of an energy storage lever of the breaker operation mechanism. When the breaker operation mechanism stores energy, the movable pin of the energy storage lever rotates anticlockwise, and the spring is in a released state; and when the operation mechanism releases energy, the movable pin rotates clockwise, the spring is stretched, the pull bar rotates due to an upward force, and the counter completes once counting. The operation counting device is simple in structure, the operation frequency is convenient to read, impact on the counter in the mechanism operation circulation process can be reduced due to elastic connection of the spring, and the reliability is improved.
Description
Technical field
The present invention relates to a kind of omnipotent breaker, particularly relate to a kind of omnipotent breaker operation count device.
Background technology
Omnipotent breaker is used for distributing the impact that electric energy and protective circuit make it from faults such as overload, short circuit, under voltage, ground connection in a power distribution system.The reliability of omnipotent breaker, will directly have influence on the fail safe of distribution system and supply electrical stability.Operational cycle number of times is the important indicator weighing breaker reliability, for avoiding unnecessary power failure, stops potential safety hazard, and circuit breaker should use under the operational cycle life-span of regulation, the circuit breaker that should more renew in time after reaching certain number of operations.Therefore people design the operation count device of various omnipotent breaker.
But, the shortcoming of existing omnipotent breaker operation count device ubiquity complex structure and reliability difference.
Summary of the invention
The object of the present invention is to provide a kind of omnipotent breaker operation count device, the complex structure existed with the operation count device solving omnipotent breaker in prior art, the problem of reliability difference.
For reaching this object, the present invention by the following technical solutions:
A kind of omnipotent breaker operation count device, it comprises support, counter, pull bar and spring, wherein, described support is fixed on circuit breaker operation mechanism, described counter is fixed on described support, one end of described pull bar is connected on the main shaft of described counter, one end of other end linking springs, and the other end of described spring is connected on the removable pin of energy storage lever of circuit breaker operation mechanism.
Especially, described support is bent into " L " type structure by sheet metal punching, comprise stationary plane sum counter installed surface, stationary plane is fixed on the side plate of circuit breaker operation mechanism by hold-down screw by described support, and described counter is fixed on described counter installed surface by screw.
Especially, one end of described pull bar offers installing hole, the through hole of strip is offered between this end of described installing hole and described pull bar, this end of described pull bar is divided into the first clamping section and the second clamping section, on first and second clamping section described, correspondence offers fixing hole, the main shaft of described counter is through described installing hole, the main shaft of counter is fixedly connected with described pull bar through the fixing hole on first and second clamping section by hold-down screw, the other end of described pull bar offers spring connecting hole, and one end clasp joint of described spring is in described spring connecting hole.
Especially, described removable pin offers stopper slot, one end clasp joint of described spring in described stopper slot, to facilitate this end of fixing spring.
Beneficial effect of the present invention is, compared with prior art described omnipotent breaker operation count device can realize calculating the accumulation of omnipotent breaker operational cycle number of times.During circuit breaker operation mechanism energy storage, the removable pin on mechanism's energy storage lever rotates counterclockwise, and spring is in release condition; When energy once released by operating mechanism, removable pin rotates clockwise, and spring is stretched, and the active force produced upwards makes pull bar rotate, and rolling counters forward once.Not only structure is simple, and number of operations is convenient to reading directly perceived, and due to spring be that elasticity connects, can impact to counter in reducing mechanism operational cycle process, improve reliability.
